# Purpose
#
# To run all tests possible or available on the platform.
#
# Warning: the test is destructive. It includes various build modes and
# configurations, and can and will arbitrarily change the current CMake
# configuration. After this script has been run, the CMake cache will be lost
# and CMake will no longer be initialised.
#
# The script assumes the presence of gcc and clang (recent enough for using
# ASan with gcc and MemSan with clang, or valgrind) are available, as well as
# cmake and a "good" find.

# Abort on errors (and uninitialised variables)

#
# Test Suites to be executed
#
# The test ordering tries to optimize for the following criteria:
# 1. Catch possible problems early, by running first tests that run quickly
#    and/or are more likely to fail than others (eg I use Clang most of the
#    time, so start with a GCC build).
# 2. Minimize total running time, by avoiding useless rebuilds
#
# Indicative running times are given for reference.
